we will be contagious from day 3

Type omicron Different from the delta variant or the original strain of Covid-19. Whereas Omicron has been shown to contain less severeA new study conducted by Centers for Disease Control and Prevention (CDC) – the US public health system – has proven that sick people can be well previously infectious compared to other strains.

In fact, we remember that incubation Omron’s will be smaller than other variants. With the original strain of Sars-CoV-2, hosts usually develop symptoms six to seven days after infection, or in rare cases up to fourteen days.

With Delta, the time to onset of symptoms was already shortened and was like four or five days.

However, if you are infected with the Omicron type, you may have symptoms. two to three days after infection, indicates CDC. A study that allowed US experts to understand when a patient is most contagious.

Omicron: The peak of infectivity is between 3 and 6 days

If Omicron is able to produce traits rapidly, it would be because one of its properties would enable it attack our cells fast, The second hypothesis would be that the immune systems of vaccinated people would react more quickly, causing symptoms relatively quickly. This theory may explain why so many vaccinated people are among the victims of the Omicron variant. However, it is ensured that most of the forms are mild or moderate.

The CDC joined a Japanese study that also looked at the viral loads of people infected with Omicron and found that when the host would be most contagious will intervene from the third day of infection Between three and six days after the onset of symptoms, you are more likely to spread the disease.

With Delta, the peak was between two days before and two days after the onset of symptoms.

The Japanese study was done on 21 patients infected with Omicron and it is estimated that it was only from tenth day that the viral load is significantly reduced.

O’Micron: When would be a good time to test?

The Japanese researchers also analyzed various PCR test samples. According to their results, some testing Can be positive when samples contain only dead pieces of virus.

Their results also confirmed that the virus can be present and survive for up to nine days after the onset of symptoms. In other words, some patients were still infectious nine days after the onset of symptoms. If with Omicron we can have symptoms faster than before, then symptoms will be followed by a peak of infectivity, as was seen with delta, alpha and historical strains.

Another Taiwanese study conducted by Central Epidemic Command Center Turns out that all patients still had high viral load – and so were probably always contagious – Onset of symptoms eight days after their infection or with Omicron.

Researchers from American, Japanese and Taiwanese studies have indicated that Contact cases should self-test between five and nine days After the last risky contact. The results of these studies may thus explain why so many patients present a negative self-test result on D+4 and turn positive a few days later.
